The Poll is like a one question survey. There is a textbox above the "Add To Options" button, you need to type the option text there before clicking the button, then it appears in the listbox. The pencil icon is only used after items are in the listbox, you click the item, then click the pencil to edit the existing item.
The workflow of the poll is a bit convoluted you have to activate the poll to get it working once the options have been added.
Hope that helps,
